摘要：
FIELD: medicine.SUBSTANCE: invention refers to medical equipment, namely to cardiovascular surgery, particularly for removal of infected, broken and prognostic dangerous endocardial electrodes previously implanted in the heart through a blood vessel. Locking stylette device for extracting an endocardial electrode of the pacemaker comprises cylindrical body 1, one end of which is configured to receive electrode 10 in the lumen, consisting of a movable and a fixed portion relative to electrode 10, rod 5, actuator of rod 5 and handle 7. According to the invention, the outer surface of the distal end of cylindrical housing 1, on the side of its location in the lumen of electrode 10, is made bevelled to form an outer cone-shaped surface, on which capturing cap 2 with longitudinal slots 8 is rigidly connected to tie-rod 5. Inner edge of capturing cap 2 is bevelled to form inner cone-shaped surface coinciding in size and shape with outer cone-shaped surface of distal end of cylindrical housing 1. Rod 5 displacement actuator is made in the form of a screw pair including proximal stop 4 rigidly connected to rod 5, and nut 5 located between proximal stop 4 and entering into screw connection with distal stop 6, rigidly connected with movable part of cylindrical housing 1.EFFECT: improving convenience during electrode extraction with simultaneous minimization of applied forces at its extraction.4 cl, 4 dwgИзобретение относится к медицинской технике, а именно к сердечно-сосудистой хирургии, в частности для удаления инфицированных, сломанных и прогностически опасных эндокардиальных электродов, ранее имплантированных в сердце через кровеносный сосуд. Устройство запирающего стилета для экстракции эндокардиального электрода электрокардиостимулятора включает цилиндрический корпус 1, один конец которого выполнен с возможностью размещения в просвете электрода 10, состоящий из подвижной и неподвижной частей относительно электрода 10, тягу 5, исполнительный орган перемещения тяги 5 и руч
